From 23699f98f84f20195fddd0263d05a8ccb8694676 Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Sat, 2 Oct 2010 14:03:32 +0200 Subject: spi: spi-gpio.c tests SPI_MASTER_NO_RX bit twice, but not SPI_MASTER_NO_TX The SPI_MASTER_NO_TX bit (can't do buffer write) wasn't tested. This code was introduced in commit 3c8e1a84 (spi/spi-gpio: add support for controllers without MISO or MOSI pin). This patch fixes a bug in choosing which transfer ops to use.
